The short answer: If you are asking can i put baking soda in cat litter, the answer is yes, in small amounts, for most healthy cats. Sprinkle a thin layer on the bottom of a clean box before adding litter, not a thick dusting on top. But baking soda is a minor helper, not a fix. Daily scooping, enough boxes and a firm-clumping unscented litter do far more for odor, and a litter with baking soda already blended in is the simplest option.
This guide is research based. It draws on a vet-reviewed article from Hepper, shelter guidance from the ASPCA and a litter roundup from Catster. It is general information, not veterinary advice.
Does Baking Soda Help With Litter Box Smell?
Baking soda absorbs some odor, which is why many clay litters include it. The ASPCA even lists baking soda as an option when washing the box. It works best as a background helper in a box that is already scooped daily.
What it cannot do is cancel out urine left sitting for days. The main source of smell is urine that stays in the box, and only scooping removes that.
Is It Safe to Put Baking Soda in Cat Litter?
A light layer is generally considered fine for healthy adult cats, but there are real cautions. The vet-reviewed Hepper article goes further and says baking soda should not be your first choice for a smelly box. It points to:
- Swallowing it. Small amounts are considered safe, but large amounts can be harmful, and there is little research on long-term effects of cats ingesting it while grooming paws.
- Dust. Fine powder gets kicked into the air when a cat digs, which can bother sensitive airways.
- Sensitivity. Watch for sneezing or extra grooming and stop if you see it.
- Little benefit with good clumping litter, which already traps moisture well.
Skip baking soda in kitty litter for cats that eat litter, kittens, cats with breathing problems, and cats your vet has put on a special diet for heart or kidney conditions. When in doubt, ask your vet.
How to Use It Safely
- Start with a clean, dry box.
- Sprinkle a thin, even layer on the bottom, just enough to lightly cover it.
- Add litter on top so your cat’s paws do not touch the powder directly.
- Do not stir it through or dust it on top, which raises dust and puts it on paws.
- Watch your cat for a few days. If your cat sniffs and leaves, sneezes, or goes next to the box, stop.
Using baking soda for litter box washing is a gentler option: scrub the empty box with warm water and a little baking soda, then rinse well.
Better Options for Odor
- Scoop every day. Hepper calls regular cleaning the most effective way to control odor.
- Use a firm-clumping unscented litter, so urine leaves the box in clumps.
- Have enough boxes: one per cat plus one.
- Change the litter on schedule. Our guide on how often to change kitty litter explains the timing.
- Ventilate the area around the box.

Quick Answers
Can you put baking soda in cat litter that already contains it?
There is little point. Litters with baking soda already include it in a measured amount.
Is baking soda for cat litter better than scented litter?
It is usually kinder to cats than strong perfume, since many cats dislike scent. Neither replaces scooping.
Can I use baking soda in litter box liners or automatic boxes?
Check the maker’s instructions first. Powder can clog sensors and screens in self-cleaning boxes.
The Bottom Line
So, can i put baking soda in cat litter? Yes, a thin layer under the litter is usually fine for healthy cats, but stop if your cat reacts, and do not expect it to solve odor on its own. Scooping, good litter and enough boxes do the heavy lifting. For more help, see our litter and odor guides.
